I know that quoting yourself is kind of gauche but I just wanted to share my experiences on the install, I had tried to do this last night but I kept getting the different "file/directory not found errors." even with the latest zip. I did try and reinstall RC1 but that didn't correct the issues, so finally I had to do a data/cache wipe, install the latest CW updates, install the version 1.19.0 of Busybox (I did have 1.19.3) and the Busybox installer app kept erroring out until I went in and manually deleted the file from both bin and xbin. Short story long, I did get a successful install of PB 2.2 (I did have to manually copy the unzipped files to the correct locations on the SD card) and it appears that all of the mods are running correctly except for Cron (it give me an error under check mods) but I'm not worrying about that much since that has been reported by others also. One other thing, I did the PB install before I signed back into the Market just to minimize the number of variables that could cause a bad install. So now I'm in the process of recovering all my Apps and getting the DX back to where it was. Just thought I would pass my experiences along to the community.
Thanks to BMC for all his great work in coming up with PB and all the other things he does.
Cheers.
